Introduction

ASRock Radeon RX 7600 Phantom Gaming OC is a premium custom-design rendition of AMD's latest mid-range graphics card. The RX 7600 is meant for 1080p AAA gaming with high to max settings, plus you can take advantage of AMD features such as FSR 2 to further improve performance. The Phantom Gaming series by ASRock is geared toward gamer aesthetics, with plenty RGB bells and whistles, and a racy design and a factory overclock to boot. The RX 7600 is based on AMD's latest RDNA 3 graphics architecture, which means you get all of the innovations AMD introduced with this series, including the much more capable RDNA 3 Dual Compute Unit, second generation Ray Accelerator for generational ray tracing performance improvements, and hardware acceleration for AI.



While the Radeon RX 7600 is based on RDNA 3, the Navi 33 silicon at its heart is built on the older 6 nm foundry process, and not the newer 5 nm EUV powering the RX 7900 series. AMD calculates that in this segment, it doesn't really need the latest foundry node, and can achieve the desired power-draw and performance/Watt using the older node. What's also interesting, is that the Navi 33 die has numerically the same number of shaders as its predecessor. AMD intends for the RX 7600 to be seen as a successor to the RX 6600, and not the RX 6600 XT or RX 6650 XT, and because the RX 7600 maxes out the Navi 33 silicon, there is a generational increase in shaders compared to the RX 6600.

The Navi 33 silicon features 32 RDNA 3 compute units, which work out to 2,048 stream processors, 32 Ray Accelerators, 64 AI Accelerators, 128 TMUs, and 64 ROPs. The memory size is unchanged at 8 GB, as is the 128-bit memory interface, and the 32 MB Infinity Cache size, although AMD has stepped up the memory speed to 18 Gbps, and the second generation Infinity Cache runs faster. There are other architectural innovations to be had, such as the AMD Radiance Display Engine, and hardware AV1 encoding capabilities. The ASRock RX 7600 Phantom Gaming OC features an upmarket design that looks like it belongs to a segment above, with its triple-fan layout. You get factory overclocked speeds in the shape of a 2356 MHz Game clock, compared to 2250 MHz reference, while the memory speed is left untouched at 18 Gbps. ASRock hasn't given us any pricing guidance, so we'll be assuming a $40 price premium throughout this review.
